Definition

The term "Block Reward" refers to the incentive given to miners or validators for successfully adding a new block to a blockchain. This reward typically consists of newly minted cryptocurrency and transaction fees from the transactions included in the block.

Why it matters

• It incentivizes network participants to secure the blockchain.
• It helps in the distribution of new coins into circulation.
• The block reward can influence the overall supply and demand dynamics of a cryptocurrency.
• Changes in block reward can affect miner profitability and network security.

Risks & Pitfalls

• A decrease in block rewards may lead to reduced miner participation.
• Fluctuations in reward can impact transaction fees and network congestion.
• Dependence on block rewards can create vulnerabilities in the network's economic model.

Examples

• In Bitcoin, the block reward halves approximately every four years, impacting the supply of new coins.
• Ethereum transitioned from a block reward model to a proof-of-stake system, altering its incentive structure.
